Objective To investigate the application value of ultrasound guided cut needle biopsy from external cervical path in diagnosis of parapharyngeal space neoplasms.Methods Forty-three cases of parapharyngeal space neoplasms underwent ultrasound guided cut needle biopsy from external path of neck were enrolled in this study.Diagnostic accordance rate of biopsy histology were compared with pathology after surgery.Results Among 43 cases,the consistency rate of biopsy compared with surgical pathology was 97.7%(42/43).No severe complication induced by biopsy was found.Conclusion With high accuracy and few postoperative complications,ultrasound guided cut needle biopsy from external path of neck is a simple and safe way to diagnose parapharyngeal space neoplasms.%目的 探讨超声引导下颈外路径切割组织穿刺活检术在咽旁间隙肿瘤诊断中的应用价值.方法 回顾性分析43例咽旁间隙肿瘤患者经超声引导下颈外路径切割组织穿刺活检情况,判断穿刺结果 与术后病理结果的诊断符合率.结果43例患者中42例穿刺病理结果与术后病理结果一致,穿刺活检的诊断准确率97.7%,所有患者均无并发症.结论 超声引导下咽旁间隙肿瘤颈外路径切割组织穿刺活检操作简单,用时短,穿刺结果与术后病理符合率高,术后并发症少,对咽旁间隙肿物的术前定性诊断有一定临床应用价值.
